MOTOR SUSPENSION.

SPECIFICATION forming part of Letters Patent No. 644,213, dated February27, 1900.

Application filed August 22, 1899. Serial No. 728,070. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, EDWIN G. NICEWANER, of J ohnstown, in the county ofCambria and State of Pennsylvania, have invented a new and usefulImprovement in Motor Suspensions, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to motor suspensions, and is designed to providemeans of novel character for elastically connecting and supporting apair of electric motors sleeved at one end to opposite axles of acar-truck, the connection and support being independent of both thecar-body and the truck-frame.

With this object in View the invention consists in the combination, witha pair of electric motors, ofan elastic member extending from one motorto the other and supported at its ends upon the motor frames or casings,with connections between the said member and the nose or free end ofboth motors.

The invention also consists in the novel construction and combination ofparts, all as hereinafter described and shown.

The invention is particularly applicable to double trucks or othertrucks having a comparatively-short Wheel-base.

Referring to the accompanying drawings, Figure 1 is a side View, partlyin section, of a car-truck and motors having my improved suspension; andFig. 2 is a plan view of the same. Fig. 3 is a detail view. In thesefigures I have omitted the truck-frame, which may be of any approvedconstruction and which forms no part of my present invention.

The letters A A designate the two motors, each of which is sleeved inthe usual manner to an axle B of the truck. 0 designates an elasticmember which connects the two motors and which consists, preferably, ofa se mielliptic spring, as shown. The motors are each provided with aseat for the respective ends of this spring. In the construction shownthese seats are formed by projections D, overhanging the axles andhaving sockets to receive the end portions of the springs.

Each motor frame or casing is provided at its nose end with a suitablelug or hook E' to receive a tie connection or loop F, whose upper end isengaged with the spring 0. To secure these tie-loops; the upper shortleaf of the spring may be formed with hooked ends f. These loops havecross-bars, as shown in Fig. 3, for bearing engagement with the noselugsand with the spring.

I preferably employ two of the springs 0, arranged substantially asshown in Fig. 2.

By the means described I provide a suspension for the motors whicheffectively cushions them against movements due to torque and trackunevenness, while it permits such movements to a limited extent. I alsoprovide a suspension which is independent of the carbody and also of thetruck-frame and which is therefore not affected by the movements ofeither.

I do not wish to limit myself to the particular construction which Ihave herein shown and described, as the same may be varied withoutdeparting from the spirit and scope of my invention.

Having thus described my invention, what I claim, and desire to protectby Letters Patent, is-

1. The combination with two electric motors each sleeved to an oppositeaxle of a truck, of an elastic connecting member rested at its ends uponthe motor frames or casings, and connections between said member and thenose ends of both the motors.

2. The combination with two electric motors each sleeved to an oppositeaxle of a truck, of a spring rested at its ends upon the motor frames orcasings, and ties connecting the spring with the nose ends of themotors.

3. The combination with two electric mo tors, each sleeved to anopposite axle of a truck, of a semi-elliptic spring rested at its endsupon the tops of the motor frames or casings and loops engaging the saidsprings and lugs or projections at the nose ends of the said frames orcasings.

4. The combination with two electric motors each sleeved to an oppositeaxle of a truck, having lugs at their nose ends, and also projectionsoverhanging the truck-axles, of a spring resting at its ends upon thetops of the motors and engagingthe said projections, and ties connectingthe nose-lugs with the said spring. Y

5. The combination with two electric motors each sleeved to an oppositeaxle of a truck, of a pair of springs resting at their ends upon thesaid motors and engaging lugs or projections thereof, and tiesconnecting the nose end of each motor with both of the said springs.

6. The combination with two electric motors each sleeved to an oppositeaxle of a cartruck, of a spring whose ends bear upon the tops of themotor frames or casings at one side of the centers of gravity of themotors, and connections between the said springs and the motors at theopposite sides of their centers of gravity.

7. The combination with two electric motors each sleeved to an oppositeaxle of a cartruck, of a spring Whose end portions are supported by themotors, and connections between the said spring and the nose end of bothmotors.

8. The combination with two electric n10 tors each sleeved to anopposite axle of a cartruck, and having their frames provided with lugsat their nose ends, and also with socketed projections overhanging thetruck-axles, of a spring whose end portions engage the sockets of saidprojections, and tie-loops engaging the said springs and also thenose-lugs of the motors.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
